42EF Photoelectric Sensors
IO-Link functionality, brighter LEDs and other enhancements
Rockwell Automation announces enhancements to the 42EF RightSight™ line with the introduction of embedded IO-Link functionality along with many new features. IO-Link allows sensors to easily integrate into The Connected Enterprise, delivering data from the sensor directly into a control system in a very cost efficient and easy-to-use manner via an IO-Link Master and EtherNet/IP™.
The Allen-Bradley®42EF RightSight with IO-Link features a new user interface boasting ultra-bright LEDs that are visible from 360° up to 7 m (23 ft) away for clear status indication during setup, operation and troubleshooting. The visible red light source, linear sensitivity adjustment and industry-leading form factor with 18 mm threaded base and nose mount make RightSight a flexible, easy-to-use sensing solution. Plus, the rugged IP69K rated housing and improved high frequency ballast immunity ensure reliable sensing in the toughest industrial environments.
Connecting the 42EF RightSight to an IO-Link master also allows you to take advantage of advanced sensing functionality including real-time diagnostics, automatic device configuration (ADC) and access to multiple configurable parameters that help minimize downtime and increase productivity.

What is IO-Link?
IO-Link is a worldwide open-standard protocol that allows sensors to easily integrate into The Connected Enterprise. Benefits of IO-Link technology include:• Reduced inventory and
operating costs• Increased uptime/productivity• Simplified design, installation, setup
and maintenance• Enhanced flexibility and scalability
IO-Link enabled sensors offer advanced features and diagnostics that can only be accessed through an IO-Link master. These sensors act like standard sensors when not interfaced to an IO-Link enabled control system, so you can stock the same sensors for standard I/O (SIO) applications and IO-Link applications, simplifying the selection process and reducing stocking costs.
Product Selection Additional product selection available on http://ab.rockwellautomation.com/.
42EF, IO-Link Version 1.1• IO-Link is a worldwide open-standard peer-to-peer
serial communication protocol (IEC 61131-9) that allows sensors and actuators to easily integrate into The Connected Enterprise.
• The IO-Link enabled 42EF sensor—when connected to an IO-Link master—shares device identity, parameters, real-time diagnostics and process data with the control system to optimize machine setup, maintenance and troubleshooting.
• By combining simple implementation with powerful data and diagnostics, IO-Link sensors provide simplified integration and seamless visibility of your processes to increase uptime and productivity. 1734 POINT IO Master
for POINT I/O™
42EF IO-Link Benefits• Sensor Heartbeat helps ensure reliable operation by
indicating sensor failure or faulty wiring to the PLC.
• Low Margin Bit Indication minimizes downtime by notifying the user when the lens is getting dirty and needs to be cleaned.
• Signal Strength provides the raw measurement value of the amount of light reflected from the target.
• Margin Levels display the excess gain above the sensor’s threshold to ensure reliable detection of the target.
• Process Data Maps allow users to select the type of information that should be continuously sent to the PLC as a process data parameter.
Note: IO-Link Master Module (Catalog No. 1734-4IO1 or 1732-8lOLM12R) is required for premier IO-Link integration experience.IO-Link enabled
Visible Beam: The bright red LED light source ensures easy alignment
Universal Mounting: Industry standard 18 mm threaded base mount and nose mounts maximize application flexibility
Ultra-Bright LED User Interface: New User Interface LEDs allow for a highly visible 360º indication of sensor status at distances of up to 20 m away
Linear Potentiometer Adjustment: Simplifies sensor setup and commissioning since any change in the potentiometer is directly proportional to the sensing range
